Maths Symbols Uses with Examples

+ (Plus): Represents addition. Used to combine quantities. Example: 5 + 3 = 8
– (Minus): Represents subtraction. Used to find the difference between quantities. Example: 10 – 4 = 6
× (Multiplication): Represents multiplication. Used to find the product of numbers. Example: 3 × 7 = 21
÷ (Division): Represents division. Used to find the quotient of numbers. Example: 12 ÷ 3 = 4
= (Equal): Represents equality. Used to show that two expressions have the same value. Example: 2 + 2 = 4
< (Less than): Indicates that one quantity is smaller than another. Example: 5 < 8
> (Greater than): Indicates that one quantity is larger than another. Example: 10 > 7
π (Pi): Represents the ratio of a circle’s circumference to its diameter. Used in geometry and trigonometry. Example: Circumference = π × Diameter
∑ (Summation): Represents the sum of a sequence of numbers. Used in calculus and series. Example: ∑(i=1 to 5) i = 1 + 2 + 3 + 4 + 5 = 15
∆ (Delta): Represents a change or difference. Used in calculus and science. Example: Δx represents the change in x.
√ (Square Root): Represents the principal square root of a number. Used to find the value that, when multiplied by itself, gives the original number. Example: √25 = 5
% (Percent): Represents a proportion out of 100. Used to express percentages. Example: 25% = 25/100 = 0.25
∈ (Belongs to): Indicates that an element belongs to a set. Example: x ∈ {1, 2, 3} means x is an element of the set {1, 2, 3}.
∞ (Infinity): Represents an unbounded quantity. Used in calculus and limit concepts. Example: lim(x → ∞) 1/x = 0
≠ (Not Equal): Indicates that two quantities are not equal. Example: 7 ≠ 10
° (Degree): Represents a unit of measurement for angles. Example: A right angle measures 90°.
≈ (Approximately Equal): Indicates that two quantities are nearly equal, but not exactly. Example: π ≈ 3.14159
∠ (Angle): Represents a geometric angle formed by two rays. Example: ∠ABC represents the angle at vertex B between rays BA and BC.
∴ (Therefore): Used to indicate a logical conclusion or implication. Example: If x = 3, and y = 2x + 1, then y = 7. ∴ y is equal to 7.
∵ (Because): Used to introduce the reason or cause for a statement. Example: ∵ x = 5 and y = x + 3, therefore y = 8.
∫ (Integral): Represents the concept of integration in calculus. Example: ∫ f(x) dx represents the integral of the function f(x) with respect to x.
∇ (Nabla, Gradient): Represents the gradient operator in vector calculus. Example: ∇f represents the gradient of the scalar function f.
∂ (Partial Derivative): Represents a partial derivative in calculus. Example: ∂f/∂x represents the partial derivative of the function f with respect to x.
∩ (Intersection): Represents the intersection of sets. Example: A ∩ B represents the set of elements that are in both sets A and B.
∪ (Union): Represents the union of sets. Example: A ∪ B represents the set of elements that are in either set A or set B.
∴ (Logical AND): Represents logical conjunction in propositional logic. Example: P ∧ Q is true if both propositions P and Q are true.
∨ (Logical OR): Represents logical disjunction in propositional logic. Example: P ∨ Q is true if at least one of the propositions P or Q is true.
~ (Tilde, Negation): Represents logical negation or bitwise NOT. Example: ~P is true if proposition P is false.
⇒ (Implies): Represents logical implication. Example: If it is raining (P), then the ground is wet (Q). P ⇒ Q.
∀ (For All): Represents universal quantification in logic. Example: ∀x, x > 0 means “For all x, x is greater than 0.”
